Fibre-optic delivery of time and frequency to VLBI station
free download

ABSTRACT The quality of Very Long Baseline Interferometry (VLBI) radio observations predominantly relies on precise and ultra-stable time and frequency (TF) standards, usually hydrogen masers (HM), maintained locally at each VLBI station. Here, we present an

Fibre-optic metadevice for all-optical coherent signal processing at 40 Gbit/s
free download

AbstractWe demonstrate a fully functional metadevice performing coherent all-optical logical operations including NOT, AND and XOR at up to 40 Gbit/s at wavelengths between 1530 nm and 1565 nm and demonstrate that the underlying mechanism has a bandwidth of

Distributed fibre-optic monitoring of an Osterberg-cell pile test in London
free download

This paper presents a case study of an Osterberg-cell test of a pile located at the Isle of Dogs in London, which was heavily instrumented with distributed optical-fibre sensors, strain gauges, displacement transducers and extensometers. Special emphasis is given on the

AGIFAMOR Application of distributed acoustic and fibre optic sensors for continuous monitoring of pipes
free download

Abstract Pipelines and industrial piping systems are particularly relevant regarding technical safety, availability and maintenance. Large flow rates of hazardous substances imply that even smallest leakages can lead to high environmental impacts. Therefore, and to ensure

Conveyor fire detectioncondition monitoring using fibre optic distributed temperature sensing (DTS)
free download

SUMMARY Traditional fire detection on and around mine and process plant conveyors has been difficult to achieve using conventional point heat detectors and aspirating CO gas detectors. This is mainly due to the conveyors long length and variable physical orientation

Direct Downhole Temperature Measurement and Real Time Pressure-Enthalpy Model Through Photon Counting Fibre Optic Temperature Sensing
free download

ABSTRACT Temperature, pressure and enthalpy data is very important and valuable, both during geothermal drilling and in well operation. We research the possibility of direct downhole measurement of temperature, free calibration, which will result in a real time

A circulator fibre-optic memory loop using an additional opposite-flow channel
free download

Abstract. A method for enhancing information capacity and reliable storage of the information in circulator fibre-optic memory systems is presented. For this purpose an additional channel with opposite-direction circulation of the signals is provided. The

Signal detection for communication over the nonlinear fibre-optic channel
free download

The nonlinear Fourier transform (NFT) is a recently rediscovered method [1] that allows solving analytically the nonlinear Schrödinger equation (NLSE), which describes the propagation of an optical signal in an optical fiber. The NFT can be used to design novel

Reduced fibre density in the visual pathways of multiple sclerosis patients with optic neuritis
free download

Synopsis Axonal degeneration is a key pathological driver of disability in multiple sclerosis (MS). Treatments aiming to reduce or reverse axonal degeneration in MS require sensitive and specific markers. Here we explore putative fibre-specific markers of axonal CSE PROJECTS
